摘要： 结晶-非晶高聚物共混体系的相容性和结晶行为的研究已有许多报道。本工作研究了含酞侧基聚芳醚酮(PEK-C)与聚苯硫醚(PPS)共混物的相容性和结晶行为。 PEK-C为徐州工程塑料厂产品,未作封端处理,ηsp/c=0.70;PPS为日本东丽产品。两者用双螺杆挤出机在320～350℃制成共混物。仪器为Perkin-Elmer DSC-7型差示扫描量热仪,升温速率10℃/min;DDV-Ⅱ-EA型全自动动态粘弹谱仪和理学D/max-ⅡBX-射线衍射仪。

关键词: 酞侧基聚芳醚酮, 聚苯硫醚, 相容性, 结晶行为

Abstract: The blends of polyether-ether ketone with cardo group (PEK-C) with polyphenylene sulfide (PPS) were prepared by melt-blending. The miscibility and crystalline properties of PEK-C/PPS blends have been investigated by DSC, WAXD and DMA. PEK-C was found to be immiscible with PPS. The cryrtallization temperatures of blends were 5～10℃ lower than that of the pure PPS. The degree of crystallinity of PPS in the blends increased with the increase of PEK-C content, which does not affect the unit cell parameter of PPS.

Key words: polyether-ether ketone with cardo group, polyphenylene sulifde, miscibility, crystallization behaviour
